And when he attained his maturity and became full grown, We granted him wisdom and knowledge; and thus do We reward those who do good (to others). 14 He entered the city unnoticed by its people, and there he encountered two men fighting with one another -- one of his own people and the other one of his enemies. The one who belonged to his own people cried out to him for help against his foe -- whereupon Moses struck him down with his fist, thereby causing his death. Moses said, "This is Satan's doing; he is an open foe, leading man astray." 15 He said, "My Lord, indeed I have wronged myself, so forgive me," and He forgave him. Indeed, He is the Forgiving, the Merciful. 16 He said: My Lord! Forasmuch as Thou hast favoured me, I will nevermore be a supporter of the guilty. 17 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 18 So when he desired to seize him who was an enemy to them both, he said: O Musa! do you intend to kill me as you killed a person yesterday? You desire nothing but that you should be a tyrant in the land, and you do not desire to be of those who act aright. 19 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
